Abstract(s) :

(Français) The paper presents the results of a study of 6,263 specimens of Xylocopinae caught in Belgium, France and Corsica, from personal collection and from 63 different institutions and private collections.Eleven species of the genus Ceratina and four species of the genus Xylocopa belong to the French fauna of Xylocopinae. Only two of those species are present in Belgium: Xylocopa violacea (L.) et Ceratina cyanea (Kirby). A new subgenus of the genus Ceratina is described: Dalyatina n. subg. The Mediterranean species Ceratina parvula Smith, present in France (as well as six other species from subsaharian Africa) is included in that new subgenus. For each genus, subgenus and species, the authors give a diagnosis, a differential diagnosis, a list of visited fl owers, a list of the nesting substrates,a map showing the French distribution, a graph of the phenology and a key to genera, subgenera and species. The systematics, biogeography, ecology and sex-ratio of the species are presented and discussed. The Xylocopinae are shown to be strongly polylectic but show a clear preference for Lamiaceae, Asteraceae Cardueae and, for the genus Xylocopa, to Fabaceae. All the species show a phenology which extends from April to September. The sex-ratio of the majority of the species is female-biased. 120 females of C. parvula have been observed but not a single male (capture of adults on fl owers and examined nests), suggesting that, at least in France, the species could reproduce by thelitokous parthenogenesis as it is the case with C. dallatorreana Friese. The paper includes 62 line drawings, 18 SEM photos, 17 maps and 14 phenological graphs, and provides a list of 232 plant species visited by the Xylocopinae, including 176 original observations, and 171 papers cited.
